이어서 냉각콘덴서(31)에서 1차 냉각된 냉매는 과냉각장치(61)에서 2차냉각 되는데, 상기 과냉각 장치(61)는 이중관으로 형성되어 중심관 부분으로는 1차냉각된 냉매가 통과하고, 외부관에는 정수장치(44)에서 퇴수되는 물이 통과되게 하여 냉매가 더욱 안정적으로 냉각되게 한다.Subsequently, the first coolant cooled by the cooling capacitor 31 is secondly cooled by the supercooling device 61. The supercooling device 61 is formed of a double pipe so that the first coolant passes through the central pipe part. The pipe allows the water discharged from the water purifier 44 to pass through, thereby allowing the refrigerant to be cooled more stably.
물탱크(41)는 증발기(21)에서 형성된 응축수와 냉각콘덴서(31)에서 배출되는 퇴수, 그리고 상수도물〈정수장치(44)를 통하여 정수된 물〉이 응축수 배출관(211)과 퇴수관(212), 그리고 급수관(213)을 통하여 공급되고, 물탱크(41)와 펌프(42) 사이의 공급관에 여과기(45)를 설치하여 열교환기에 안정적으로 물을 분무할수 있도록 한다.The water tank 41 is a condensate formed in the evaporator 21 and the discharged water discharged from the cooling capacitor 31, and tap water (water purified through the water purifier 44) is a condensate discharge pipe 211 and the discharge pipe 212 And, it is supplied through the water supply pipe 213, the filter 45 is installed in the supply pipe between the water tank 41 and the pump 42 to be able to spray water to the heat exchanger stably.

그러나 전술한 선출원발명은 다음과 같은 부분이 다소 미흡하였던 것이다.However, the above-described prior invention has been somewhat insufficient as follows.
즉 콤프레샤에서 냉매순환관을 통하여 냉매를 순환시킬 때, 냉매순환에 따른 소음이 제법 발생되어 시끄럽고, 또 동절기 기온이 크게 떨어지면 냉매의 온도가 더욱 급강하여 간혹 냉매가 결빙되거나 성애가 발생하여 원활하게 작동하지 못하는 폐단이 따랐다는 것이다.In other words, when the refrigerant is circulated through the refrigerant circulation tube in the compressor, the noise caused by the refrigerant circulation is quite loud, and when the temperature in winter decreases significantly, the temperature of the refrigerant is sharply increased, and thus the refrigerant sometimes freezes or freezes to operate smoothly. It was a failure to follow.
따라서 하절기 냉방시에는 냉매순환시 발생하는 소음이 크고, 동절기 난방시에는 냉매순환에 따른 소음과 더불어 간혹 온도가 크게 내려간 날에는 냉매의 결빙이나 성애발생으로 인하여 제대로 작동하지 못하는 등의 폐단이 따를 수 밖에 없었다.Therefore, the noise generated during refrigerant circulation during summer cooling is high, and the noise caused by refrigerant circulation during winter heating, as well as the occasional closure, such as malfunction due to freezing or freezing of the refrigerant on days when the temperature is greatly reduced. There was only.
따라서 본 발명은 전술한 종래의 제반문제점을 감안하여 안출한 것으로서,Accordingly, the present invention has been made in view of the above-mentioned conventional problems,

즉, 냉방시에는 콤프레샤(51)에 의해 냉매가 증발기(21)로 공급될 때(종래 실외기가 있는 에어콘에서는 냉매가 실외기로 돌아나오면서 냉각되었음) 냉매공급관(52)(52')와 4웨이밸브(200)의 b부분을 통하여 냉각콘덴서(31)를 통과하는 과정에서 송출휀(313)이 작동하여 실내공기를 케이스(311)의 통공부(312)를 통하여 빨아들이게 되고, 이때 빨아들인 공기는 열교환기(32)를 냉각시키면서 배출관(314)으로 배출되며, 이와 동시에 물탱크(41)의 물이 여과기(45)를 거쳐 펌프(42)에 의해 냉각콘덴서(31)내로 안개처럼 분무되면서 열교환기(32)를 냉각시켜 줌으로써 물과 공기에 의해 냉매가 1차냉각되는 것이며, 1차냉각된 냉매는 첵크밸브(400)를 거쳐과냉각장치(61)를 통과하면서 정수장치(61)에서 퇴수되는 물에 의해 2차냉각시켜주는 것이다.That is, during cooling, when the refrigerant is supplied to the evaporator 21 by the compressor 51 (in the air conditioner having the outdoor unit, the refrigerant is cooled by returning to the outdoor unit) and the refrigerant supply pipes 52, 52 'and the 4-way valve. In the process of passing the cooling capacitor 31 through the b portion of the 200, the discharge fan 313 is operated to suck the indoor air through the through-hole 312 of the case 311, wherein the sucked air is While cooling the heat exchanger (32) is discharged to the discharge pipe 314, at the same time the water of the water tank 41 is sprayed like a mist into the cooling capacitor 31 by the pump 42 through the filter 45, the heat exchanger By cooling (32), the refrigerant is first cooled by water and air, and the primary cooled refrigerant is discharged from the water purification device 61 while passing through the supercooling device 61 through the check valve 400. By secondary cooling.
또 과냉각장치(61)를 통과한 냉매는 모세관(71)을 통하여 증발기(21)로 공급되고 냉매를 냉각시킨 물은 호스등을 연결하여 외부로 퇴수시켜주면 된다.In addition, the refrigerant passing through the supercooling device 61 is supplied to the evaporator 21 through the capillary tube 71, and the water cooling the refrigerant may be discharged to the outside by connecting a hose or the like.
또한 증발기(21)를 통과한 냉매는 회수관(53)을 통하여 4웨이밸브(200)의 C부분을 거친후 콤프레샤(51)로 회수되고, 회수된 냉매는 다시 4웨이밸브(200)의 b부분을 통하여 공급되므로, 냉매가 실내기 내에서 순환되는 것이며, 냉매 냉각 방식을 공냉 및 수냉방식을 함께 적용하여 냉매 냉각을 시킴에 따라 오히려 실외기를 통하여 냉매 냉각을 시키는 것보다 냉방효율을 크게 향상시켜줄수 있게 되는 것이다.In addition, the refrigerant passing through the evaporator 21 passes through the C portion of the four-way valve 200 through the recovery pipe 53 and is recovered to the compressor 51, the recovered refrigerant is again b of the four-way valve 200 Since it is supplied through the part, the refrigerant is circulated in the indoor unit. By applying the refrigerant cooling method together with the air cooling and water cooling methods to cool the refrigerant, rather than cooling the refrigerant through the outdoor unit, the cooling efficiency can be greatly improved. Will be.
한편, 본 발명에서 냉매 냉각을 위해 사용하는 냉각수는 크게 상수도물과 응축수를 사용하게 되는데, 상수도물의 경우는 염소등을 비롯한 각종 약품과 세균, 그리고 기타 이물질이 함유되어 있으므로 그대로 사용할 경우 냉각수가 통하는 관이나 기타 수분이 닿는 부품등에 녹이나 스케일등이 발생할 염려가 있으므로 별도의 정수장치(44)를 통과하여 물탱크(41)로 공급시키고, 상기 물탱크(41)의 물을 냉각콘덴서(31)로 공급하여 분무시킬때도 미리 여과기(45)를 통과시킴으로써 내구성 증대와 안정적인 냉각작용이 이루어지게 되는 것이다.On the other hand, the cooling water used for cooling the refrigerant in the present invention is largely used tap water and condensate, in the case of tap water contains various chemicals, such as chlorine and bacteria, and other foreign substances, if used as it is a pipe through which the coolant passes Since there is a risk of rust or scale, etc. in contact with water or other moisture, such as through the separate water purification device 44 to supply to the water tank 41, the water in the water tank 41 to the cooling capacitor 31 When supplying and spraying is also through the filter 45 in advance to increase the durability and stable cooling will be made.
그리고, 부수적인 작용이기는 하지만, 물탱크(41)내의 수위감지를 위한 수위 감지호스(411)를 투명 또는 반투명으로 설치사용하여 물탱크(41)내의 수위감지가 항상 가능하게 하였고, 또 온도감지센서(412)를 설치하여 실내온도측정이 가능하게하였다.And, although it is a side effect, the water level detection hose 411 for water level detection in the water tank 41 is installed or used transparently or semi-transparent, so that the water level detection in the water tank 41 is always possible, and the temperature sensor 412 was installed to allow room temperature measurements.
한편 난방시에는 4웨이밸브(200)를 역조작시켜(이때 4웨이밸브는 a부분과 c부분이 연통되게 되고, D부분과 b부분이 연통됨) 냉매가 회수관(53)을 통하여 증발기(21)로 유입 순환되게 한후 모세관(71)을 거쳐 냉매공급관(52')으로 회수되게 하되, 상기 회수관(53)에 설치된 과냉각장치(61)가 역으로 냉매를 가열하는 장치로서의 작용을 하게 하고, 이어서 과냉각장치(61)를 통하여 회수되는 냉매를 다시 모세관(300)을 통과시킨 다음 냉각콘덴서(31)로 공급시키면 냉각콘덴서(31)가 이 경우에는 오히려 냉매를 상온으로 가열시키는 작용을 하게 되며, 상온으로 가열된 냉매는 4웨이밸브(200)의 b부분을 거쳐 D부분으로 인출되어 콤프레샤(51)로 회수되게 되는 것이다.On the other hand, during heating, the four-way valve 200 is reversely operated (in this case, the four-way valve is in communication with the a part and the c part, and the D part and the b part are in communication) and the refrigerant is evaporated through the recovery pipe 53. 21) and then to the refrigerant supply pipe 52 'through the capillary tube 71, the subcooling device 61 installed in the recovery pipe 53 acts as a device for heating the refrigerant in reverse. Subsequently, the refrigerant recovered through the subcooling device 61 passes through the capillary tube 300 again, and then is supplied to the cooling capacitor 31 so that the cooling capacitor 31 heats the refrigerant to room temperature in this case. , The refrigerant heated to room temperature is withdrawn to the compressor 51 through the b portion of the four-way valve 200 to the D portion.
즉, 난방시에는 냉매의 흐름을 역류시켜 냉방시에 증발기를 거친후 회수되는 냉매가 뜨거워지게 되는 원리를 역이용함으로써 석유등의 보조열원 없이 실내에 안정적으로 열풍을 방출시킬수 있게 하였다는 것이며, 이러한 작용이 가능하게 되는 이유는 4웨이밸브(200)와 첵크밸브(400)를 비롯하여 종래처럼 냉매가 실외기를 거쳐 냉각되는 구성이 아니고 실내기 내에서 순환되게 끔 한 구성이기에 가능해진다 하겠다.In other words, by reversing the flow of the refrigerant during heating, the refrigerant recovered after passing through the evaporator during heating becomes hot, allowing the hot air to be stably released to the room without an auxiliary heat source such as petroleum. The reason for this is to be possible because it is a configuration such that the refrigerant is circulated in the indoor unit, rather than the configuration that the refrigerant is cooled through the outdoor unit as in the prior art, including the four-way valve 200 and the check valve 400.
그리고 본 발명에서의 가장 큰 특징은 머플러(520)와 케필러리(540) 그리고 고압안전변(530)을 설치한 구성인데,And the biggest feature in the present invention is a configuration in which the muffler 520 and the capillary 540 and the high-pressure safety valve 530 is installed,
상기 머플러(520)는 통상 내부에 타공망격판이 설치되어 있기 때문에 냉매가 순환하는 과정에서 발생하는 소음과 진동을 극소화시켜줄 수 있게 되는 것이고, 이에 따라 매우 정숙한 작동이 이루어질 수 있게 하는 것이며, 케필러리(540)는 앞에서도 잠깐 설명하였듯이 콤프레샤(51)에서 나가는 고온고압가스가 상기 케필러리(540)를 통하여 증발기 쪽으로 일부유입됨으로써 냉매순환관에 작용하는 고온고압을 분산시켜 주어 냉매순환관 및 콤푸레셔를 보호 할 수 있게 되는 것이다.Since the muffler 520 is generally provided with a perforated mesh plate therein, the muffler 520 is capable of minimizing the noise and vibration generated in the process of circulating the refrigerant, thereby allowing a very quiet operation to be made, and the kefirer Lee 540 as described above for a short time as the high temperature and high pressure gas exiting from the compressor 51 is introduced into the evaporator through the kefir 540 partly to disperse the high temperature and high pressure acting on the refrigerant circulation tube and the refrigerant circulation pipe and It will be able to protect the compressor.
냉매순환관(510)을 통과하는 고온고압의 냉매에 의해 매우 심한 압력이 작용할 경우는 냉매순환관(510)에 설치된 고압안전변이 작용하여 냉매순환관(510) 및 콤프레샤(51)를 보호할 수 있게 되는 것이다.When a very high pressure acts by the high temperature and high pressure refrigerant passing through the refrigerant circulation pipe 510, a high pressure safety valve installed in the refrigerant circulation pipe 510 may act to protect the refrigerant circulation pipe 510 and the compressor 51. Will be.
따라서 냉.난방시 냉매 순환과정에서 발생하는 소음이 극소화되고, 난방시 효율을 극대화시킬 수 있음은 물론 안전성도 극대화 되어 신뢰성을 극대화 시킬수 있게 되는등 그 효과가 다대한 것이다.Therefore, the noise generated in the refrigerant circulation process during cooling and heating is minimized, and the efficiency can be maximized as well as the safety can be maximized to maximize the reliability.
이상 설명한 바와 같이 본 발명은 콤프레샤와 연결설치되는 냉매순환관에 머플러(520), 케필러리(540), 고압안전변(530)을 설치하여 소음 및 진동예방과 난방효율을 극대화시키고, 더불어 냉매순환관(510)과 콤프레샤에 지나치게 고온고압이 작용하더라도 케필러리(540) 및 고압안전변(530)에 의해 기기의 보호가 효율적으로 이루어질수 있는 매우 유용한 발명인 것이다.As described above, the present invention installs a muffler 520, a kefir 540, and a high-pressure safety valve 530 in a refrigerant circulation pipe connected to a compressor to maximize noise and vibration prevention and heating efficiency, and also refrigerant refrigerant circulation. Even if the high temperature and high pressure acts on the tube 510 and the compressor, it is a very useful invention that the protection of the device can be efficiently performed by the kefir 540 and the high-pressure safety valve 530.
